Very few improvements will greatly improve project management :
1/ Adding a simple “title” (or name, or caption, or whatever field in project structure that would be used in window title, “Switch project in window” and “Recent Projects”. If user fill this field, no more long path before project name et strange “sublime-project” extension. Simple and clean.
2/ Adding a “title pattern” field to structure project in order to allow those who want to have there project name before current file path to do so.

I have about 4 projects opened all the time on my desktop, and those two little changes would make my (working) life so easier If I can do this using a plugin (or by writing one), please tell me, I’ll do it right now…

+1 … and while you’re there… per-project settings!

There are per-project settings. Select Project->Edit, then add a “settings” object to the top level. Anything you put in that “settings” object will be merged with other settings.

oh, awesome!
